Fig. 4 is the process flow diagram that the navigation way setting up procedure is shown.At first provide the explanation of navigation way setting up procedure based on following situation: the destination in A4 (seeing Fig. 3) place setting is the facility (for example, house) that there is no place of arrival (for example, parking lot).In this situation, the navigation way setting up procedure that carries out can be equal in fact existing navigation way setting up procedure.More specifically, because there is no place of arrival in the facility of destination, therefore judge "No" in B1 place's generation, and process proceeds to B2.At the B2 place, the guiding route that represent position of controller 2 retrievals from the starting point to the facility.Subsequently, at the B3 place, the guiding route that controller 2 navigation ways are set to retrieve.
Provide the explanation of navigation way setting up procedure based on following situation: the destination in A4 (seeing Fig. 3) place setting is the facility (for example, railway station) with a plurality of place of arrival.Fig. 5 is illustrated in to have a plurality of parking lots as the diagram of the road-map around the railway station of a plurality of place of arrival.About the road-map of Fig. 5, the situation below supposing.The destination is set to railway station 32.Railway station 32 has three parking lot 32a to 32c.The position that represents in railway station 32 is place 32d.Have the traffic rules of " travelling in the right side ".Road 31 is roads that divided lane travels, and wherein is separated into two-way current direction by central partition.Vehicle is positioned at the 31a place, position on road 31, and starting point is set to position 31a.
In the situation of Fig. 5, because the railway station 32 that is set to the destination has three parking lot 32a to 32c, therefore judge that in B1 place's generation "Yes" and process proceed to B4.At the B4 place, obtain parking lot 32a to 32c positional information (as, latitude and longitude).At the B5 place, the guiding route Ra to Rc of retrieval from position 31a to parking lot 32a to 32c.
The guiding route Ra that is directed to parking lot 32a from place 31a can be described as getting off.Guiding route Ra extends from position 31a, and 33 places turn right in the intersection, extend to intersection 34 through parking lot 32a, and 34 carry out U-shaped and turn in the intersection, and arrive parking lot 32a.On the way be through the reason that parking lot 32a then arrives parking lot 32a about guiding route Ra, road 31 is routes that divided lane travels, and parking lot 32a and vehicle are positioned at the relative both sides of the central partition of road 31.
Guiding route Rb from position 31a to parking lot 32b can be described as getting off.Guiding route Rb extends from position 31a, and turn left in 33 places in the intersection, and straight line extends to parking lot 32b.Can be similar to guiding route Rb and describe guiding route Rc from position 31a to parking lot 32c.The end portion that should be noted in the discussion above that guiding route Rc has longer air line distance than the end portion of guiding route Rb.
B6 to B8 locates in following step, selects a guiding route based on predetermined alternative condition from the guiding route Ra to Rc that retrieves.More specifically, when guiding route Ra to Rc comprises a guiding route that satisfies first condition (guiding route not needs vehicle carry out U-shaped on the road around 32 at the train station turn to), select to satisfy this guiding route of first condition.When guiding route Ra to Rc comprises the guiding route that two or more satisfy first condition, select to satisfy a guiding route of second condition (guiding route is the shortest) from two or more guiding routes.When each of guiding route Ra to Rc do not satisfy first condition, select to satisfy a guiding route of second condition (guiding route is the shortest) from guiding route Ra to Rc.
In the situation of Fig. 5, guiding route Ra needs vehicle to carry out U-shaped to turn to, do not turn to and guiding route Rb and Rc do not need vehicle to carry out U-shaped.Therefore, in guiding route Ra to Rc the inside, two guiding route Rb and Rc do not need U-shaped to turn to (all corresponding to "Yes" at B6 and B7 place).By comparing guiding route Rb and Rc distance both, guiding route Rb is shown is shorter than guiding route Rc.Thereby, at B8 place's selection guiding route Rb, and be set to navigation way at B3 this guiding route Rb of place.
Example as a comparison, set forth based on following situation: what the destination was set to railway station 32 represents position 32d, and by existing navigator retrieve from position 31a to the railway station 32 guiding route.Fig. 6 is the diagram that the guiding route that is retrieved by existing navigator is shown.Should be noted in the discussion above that the road-map shown in Fig. 6 is the same with the road-map shown in Fig. 5.
Further hypothesis for from position 31a to the railway station 32 vehicles that travel, 33 places are provided with traffic sign in the intersection.Usually, such local traffic sign guides the vehicle to the locality and does not need vehicle to carry out U-shaped and turns to.Thereby very naturally, by indication vehicle in 33 places turns left in the intersection, traffic sign guides the vehicle to parking lot 32b.In such circumstances, when vehicle was followed the route guidance of existing navigator, vehicle can turn left at 33 places in the intersection, and the indication that is provided by traffic sign is not provided.Therefore the user may feel extremely odd.
Navigator 1 according to the present embodiment, navigation way is set to be directed to from position 31a the guiding route Rb of the parking lot 32b in railway station 32, and thereby do not need vehicle to carry out U-shaped on the road around 32 at the train station to turn to, and guided vehicle arrives the destination with the shortest road.Navigator 1 does not make at the train station travelling around 32 become complicated.In addition, because vehicle the route guidance of the consistent navigator 1 of the indication that provides with traffic sign is provided and can be turned left at 33 places in the intersection, thereby the user can be in the situation that do not feel to wonder and arrive swimmingly the railway station.
As shown in top exemplary situation, the navigation way setting up procedure can arrange from position 31a to the railway station 32 suitable navigation way.When starting point was different from position 31a, suitable navigation way can be different.With reference to figure 7, give an explaination based on another following situation: navigation way is set to a plurality of guiding routes from different starting points to (the serving as the destination) facility with a plurality of place of arrival.Fig. 7 is the diagram that a plurality of routes from diverse location to the railway station with a plurality of parking lots are shown.As the situation of Fig. 5 and Fig. 6, suppose that having traffic rules and the road 41,42 of " keeping the right side to travel " in Fig. 7 is all roads that divided lane travels.
As shown in Figure 7, the railway station 43 that is set to the destination has three parking lot 43a to 43c.At first, suppose that vehicle is positioned at the 41a place, position on road 41, and starting point is set to position 41a.In such circumstances, each of three guiding routes that guides the vehicle to parking lot 43a to 43c all do not need U-shaped to turn to (corresponding to "No" at the B6 place).Select the shortest guiding route at the B8 place from three guiding routes.Therefore because the guiding route Ra1 that guides the vehicle to parking lot 43a is the shortest, be set to guiding route Ra1 at B3 place navigation way.
Suppose that starting point is the position 44a on road 44.In such circumstances, each of this two guiding routes that guides the vehicle to parking lot 43a and 43b all do not need U-shaped to turn to (corresponding to "Yes" at B6 and B7 place).Select shorter guiding route at the B8 place from two guiding routes.Therefore because the guiding route Ra2 that guides the vehicle to parking lot 43a is the shortest, be set to guiding route Ra2 at B3 place navigation way.Suppose that starting point is the place 45a on road 45.In such circumstances, the guiding route that only guides the vehicle to parking lot 43c does not need U-shaped to turn to (correspond to "Yes" at the B6 place and correspond to "No" at the B7 place).Be set to guiding route Rc at B3 place navigation way.
Suppose that starting point is the position 46a on road 46.In such circumstances, each of this two guiding routes that guides the vehicle to parking lot 43b and 43c all do not need U-shaped to turn to (corresponding to "Yes" at B6 and B7 place).Therefore because the guiding route Rb1 that guides the vehicle to parking lot 43b is the shortest, be set to guiding route Rb1 at B3 place navigation way.As shown above, even when retrieving when being directed to a plurality of guiding route in railway station 43 from diverse location, also can be set to best guiding route by navigation way.
Can revise in every way top embodiment, its example is described below.
